People inside Tank Stream tunnel

Tours of the Tank Stream are available by ballot through Sydney Living Museums.

The Tank Stream served as colonial Sydney's first and main source of fresh water for almost 40 years. It's also a place of cultural significance to the Gadigal, the traditional custodians of the Sydney Cove area.

Our Tank Stream tours offer a rare link with this nationally important location. These special tours take visitors under the city along a 60 metre length of the stream and tunnel dating between 1789 and 1965.

Public Tank Stream tours are offered twice a year in cooperation with Sydney Living Museums (SLM). They're usually held around April and November.

Tickets are only available by ballot by visiting the SLM website.

Viaduct leading to building

You'll visit the viaduct on a tour of the West Ryde Boiler House.

The West Ryde Boiler House contained the engine room for the West Ryde Water Pumping Station.

It began operating in 1921 to supply water to the homes of northern Sydney suburbs. This 'industrial cathedral’ is a monument to Australia's large-scale engineering expertise. It burned hundreds of tonnes of coal delivered daily by rail. This generated steam to drive the pumps that moved water to homes and industry.

Our West Ryde Boiler House tours offer a rare opportunity to understand the important role the site served in the history of water supply in Sydney.

You'll be taken:

  • through the boiler house building
  • along the viaduct
  • into the coal bunkers at roof level.

You'll also learn about our water quality laboratories located next to the Boiler House.

Public Boiler House tours are offered twice a year in cooperation with Sydney Living Museums (SLM). They're usually held around April and November.

Tickets are only available by visiting the SLM website.

Warragamba Dam is the largest dam in Australia. It's managed by WaterNSW.

It's located about 65 kilometres west of Sydney in a narrow gorge on the Warragamba River. It supplies water to over four million people in greater Sydney and holds up to four times more water than Sydney Harbour - about 2,031 billion litres of water when full.

The dam was built by the government because of Sydney's growing population and a severe drought from 1934-42. It was finished in 1960.

By building the dam, 75 km 2 of the Burragorang Valley was flooded. This created a lake 52 kilometres long with an average depth of 105 metres. For more information about seeing the dam, visit WaterNSW
